Tie in raffle (4)
I believe the answer is:
draw
This clue is a double definition.
'tie' is the first definition.
(I know that tie can be written as draw)
'raffle' is the second definition.
(a prize draw)
'in' is the link.
(Other definitions for draw that I've seen before include "Snag" , "Sketch; attraction" , "attractive thing" , "very attractive event" , "Sketch - tie" .)
